Status up but protocol down cisco router

some situs explaine that its because the connection between interface and the other end failed to negotiate, to solve this, we need to make sure the setting between our interface and the other end configured rightly. “This could be caused by a unidirectional link of some type, a hardware/software failure on the switch, or the other side could be err-disabled or shutdown on the other side. This could also be a problem if different protocols are used for trunking(ISL vs dot1q).
